[C 01:43:22.829 NotebookApp] Could not decode 'C:\\Users\\\xc5\xed\xcf\xd4\xb9\xa2\\.jupyter' for unicode trait 'config_dir' of a NotebookApp instance.

首先，在控制台运行jupyter notebook --generate-config

接着根据你运行实际显示的路径，打开这个配置文件（可以用notepad++，submile Text3，甚至记事本等软件打开各种格式的文件），我电脑上是这个文件C:\Users\用户\.jupyter\jupyter_notebook_config.py

然后在通过搜索关键词：c.NotebookApp.notebook_dir，定位到下面这行,我的工作目录是E盘下的quant（我是宽客哈哈），然后就保存之后，就不会再出现这个问题了

就好了
